IMPROVED MACHINE FCR DRILLING AND. PREPARING WATCH-C'ASES FOR SPRING'ING',

The Schedule refe-fred to in these Lettere Patentgand making part of the lame.

Be it' known that I, J Aucuns LAURENT, of the city, county, and State of New York, have invented a new and useful Improvement in Machinery for Preparing Watch-Gases for Springing, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of thisspecication, and in which- Figure 1 vrepresents a front view of a machine constrncted in accordance with my improvement;

Figure 2, a sectional elevation of -the same, taken as indicated by the line a: :c iu fig. 1; and

Figure 3, a plan of said machine.

Figure 4 is a face view of a watch-case with its springs in' place, in illustration of the work accomplished by the machine.

.Similar letters of reference indicate corresponding parts. l Y

The object of this invention is partly to expedite thepreparation of watch-cases for the reception and attachment oftheir springs, -but mainly to provide for an interchange of work, by insuring a uniibrinity, in the preparation for springing, of any number of cases, whereby not only is the getting up of a Aquantity of work expedited, by allowing of the taking from a heap or number of springs, any one spring to it any. one of a number of cases, but whereby great facility is afbrded. for renewing the springs iu a \vatch-'-ase when required. Y

The invention consists in a combination of adjustable devices in the one machine, for preparing the case for springing, so that said work, which has heretofore been done in detail or separately, may be done at one and the same time, whereby the most perfect uniformity for any number of cases is insured, and labor and time economized; and the invention includes certain combinations of partsin said machine, for insuring both independent and collective :uljiaitment of the tools for performing the different portions ofthe work,

to suit a variety of' different-sized cases, or dierent relative arrangements of the springs; also, adjustable means for bui-ring out the case for the nose of the catch-spring to work in.

Referring tothe accompanying drawing- A represents the frame of kthe machine, and B the bed, by which the watch-case to be prepared for springing is carried, said case, (l, being placed within, and held from moving by a die, D, secured to the bed, and of which there may be an'y desired number, to suit different styles and sizes of cases.

This bed B is adjustable horizontally, by a screw, u, on a table, E, which, in its turn, is adjustable vertically by alever, b. These adjust-ments are for the purpose of setting the work iin proper relation to the several tools, and for forcing it up to the latter, under regulation of an adjustable stop, c.

' F and F are drills for making the holes for the screws d and d', which serve toattaeh thehinge and catch-springs c and f to the case; and

G is a drill for making or locating the hole h, through which the nose of the hinge-spring plays.'` This hole, after being drilled, is filed out; o r dressed to the proper shape.

H is a revolving burr, for forming or dressing thc recess i, Withinwhich the nose of the catch-spring f plays.

The drills F, F', and G, are rotated or driven by means of 4bands applied to pulleys l: k and l, secured to the tops of the drill-holders mv m and a, which are -free to rotate within or through hollow screws, I, I',

and J, made to project through and lit sliding boxes K, K', and L, by which means said drills may he in* dependeutly raised or lowered, to suit dilierent work,

and be adjusted horizontally, as required.

Thus, while the several'drill's are adjustable vertically by turning the hollow or screw-sockets I, I', and J, the boxes K, K', and L, to said screws, are adjustable horizont-ally, bymeans of screws M and N, suitable slots, o, o', and p, heilig made in the upper plate of the main framc,to provide. for such horizontal adjustrnents, the one of which, namely, that regulating the drill G, is at right angles to those regulating the Vdrills'F F', which latter drills are unitedly adjustable in reverse horizontal directions, by the one screw M, to insure their' proper relation to each other, and to different diameters of watch-case, said screw M having right and left-hand threads cnt upon it, to effect suoli double adjustment.

The severaldxills having been thus suitably' adj usted, and bed properly set, the holes for the screws d Zaud hole h, for the nose of the hinge-spring, may all be drilled at one and vthe same time, and perfect uniformity insured in operating upon a number of cases in succession, which facilitates interchanging of the cases and springs, and expedites the pertbrmance of the work, as hereinbefore referred to.

The yspecified adjustments of the drills, taken in connection with the horizontal adjustment of the bed B, and its lift of the work in feeding, till 'arrestedby the stop c, adapts the machine to all styles and sizes of work.

Simultaneously, also, with theforuiation of the hole h and holes for the screws d d', and by the same operation of lifting the bed and table by the level` b, the watch-case has its recess, t', for play of the nose ofthe catch-spring, cut or dressed in it by the rotation ot' the hun` H, that is carried by a horizontal shaft, P, driven by a pulley, fr, and working ln screw centres, s s, which are carried bya hanger, Q.

This hanger Q is adjustable, on slackeniug a lockingnut, u, along a slot in the top plate ofthe main frame, in a direction which is at right anglesl tothe axis of the shaft P, that may be adjusted longitudinally by the screw centres s s. In this way, every provision is made for varying the position of the burr to suit ALetters Patent, is

1. The combination of the drills F F, their holders m m, drill-stocks I I', and sliding boxes K K', with the right and left-handed adjusting-screw M, substantial] y as specified.

2. The combination of the drill G, its holder n, the drill-stock J, and horizontal adjusting-screw N, with the adjustable drills F F', and their holders m m, essentially as herein set forth.

3. The combination of the adjustable revolving burr H with the adjustable drills F, F', and G, and their holders, substantially as specified.

4. Tile combination of the vertically' and l|orizontally-adjust-able drills F, F', and G, and their holders, the adjustable rotating burr H, and the horizontallyadjustable bed B, made capable of vertical action, and cari ying a suit-able die, D, essentially as and for the purpose or purposes herein set forth. v
